L <br />36 <br />because channel catfish do not live in such habitats and because of the <br />long distance involved. <br />• 2. Walleyes from Highline Reservoir can be expected to survive as poorly <br />in the Colorado River as walleyes have from Rifle Gap Reservoir. The <br />trip down Mack and Salt Washes also will be long and difficult for <br />walleyes. <br />• C. Control measures to avoid escapement -None possible, water must be <br />allowed to go over spillway. Screening the spillway is not feasible. <br />V. Impact to endangered species <br />A. There is no impact anticipated to endangered species that would effect <br />• recovery because: <br />1. Channel catfish are not expected to escape from Highline Reservoir in <br />large numbers. Likewise, any escaping fish could not be expected to <br />measurably increase the size of the river catfish population, or create <br />additional impacts to endangered fishes. <br />• 2. Walleye have been in the upper Colorado River system for over 30 <br />years and have not established themselves in the river. <br />3. There are no major backwaters in the Colorado River in the vicinity of <br />the mouth of Salt Wash where escaping fish could find refuge or <br />impact endangered fishes. <br />• B. Measures to remedy an impact, including feasibility <br />1. Discontinue stocking of walleye. <br />2. Discontinue stocking channel catfish. Gradually the reservoir <br />population will diminish in size as it currently has after stocking was <br />• suspended in 1985. <br />• <br />• <br />• <br />
